sitting at a 120 deg angle is the least amount of pressure thru your spine.

I have one and like it. It’s big and doesn’t store easily, but it does fold and is very comfortable.

Backs are different and weird but ime no chair or mattress works as well as taking a walk and or lying on the floor for a while and/or hip mobility and core strength or something else.

You need a good office chair and good mattress but they are just the baseline for management.

I tweaked my lower back and sitting makes it worse. Between eventual PT, stretching, and rest it will heal but in the meantime I need to sit!

Has anyone used an antigravity chair, or another chair they could tolerate while healing a lower back injury?
